IceCube data release "Measurement of the mean number of muons with energies above 500 GeV in air showers detected with the IceCube Neutrino Observatory":
---------------------------------------------------------------------------------------

This data release accompanies results submitted to Physical Review D describing the measurement of the average multiplicity of TeV muons with IceCube. It contains the data necessary to reproduce the main plots from the paper (Figs. 7 and 9), i.e. the numerical results for the average number of muons with energies above 500 GeV as a function of primary cosmic ray energy.

For any questions about this data release, please write to analysis@icecube.wisc.edu.

Files included in this release:
    - A README file.
    - Files including data to reproduce the results plots from the paper (see below for details).
    - An example python script showing how to read and plot the data.

What is in the files icecube_Nmu500_X_Y.txt:
-----------------------------------------

Y indicates wether the file contains values obtained from experimental data (Y="data") or air-shower simulations (Y="MC").
X indicates the hadronic interaction model for which the plot is made. If Y="data", this means that the experimental data was interpreted using this model. If Y="MC", it means that the simulations were performed with this model. The three models included are Sibyll 2.1, QGSJet-II.04, and EPOS-LHC (see paper for references). The file with X="modelaverage" gives the average over the three individual results with the deviations from the average included in the systematic uncertainties.


The data is provided in the following format:
